Abstract: An encoder partitions into blocks using a set of block partition modes obtained by combining one or more block partition modes defining a partition type. The set of block partition modes includes a first partition mode defining the partition direction and number of partitions for partitioning a first block, and a second block partition mode defining the partition direction and number of partitions for partitioning a second block which is one of blocks obtained after the first block is partitioned. When the number of partitions of the first block partition mode is three, the second block is a center block among the blocks obtained after partitioning the first block, and the partition direction of the second block partition mode is same as the partition direction of the first block partition mode, the second block partition mode includes only a block partition mode indicating that the number of partitions is three.

Abstract: A coding device (100) for coding a block to be coded included in a picture is provided with a circuit and a memory. The circuit divides the block to be coded into a first sub-block, a second sub-block, and a third sub-block in a first direction using the memory, the second sub-block being located between the first sub-block and the third sub-block, prohibits the second sub-block from being divided into two partitions in the first direction, and codes the first sub-block, the second sub-block, and the third sub-block.

Abstract: A coding device (100) is provided with a circuit (160) and a memory (162) connected to the circuit (160). The circuit (160): selects, from a plurality of tables which are used, during an operation, to correct a reference motion vector into a predetermined direction using a correction value designated by an index, and which have correction values with respectively different intervals between indexes, a first table used for a partition to be coded of an image in a moving image; writes a parameter indicating a first index to be selected from among indexes included in the first table; and codes the partition using the reference motion vector corrected by means of a correction value designated by the first index.

Abstract: A coding device (100) performs division into a plurality of blocks by using a block division mode set obtained by combining one or more block division modes which define division types. The block division mode set comprises: a first block division mode in which the number of divisions and the dividing direction for dividing a first block are defined; and a second block division mode in which the number of divisions and the dividing direction for dividing a second block, which is one of blocks acquired by dividing the first block are defined. When a division in the first block mode results in three blocks, the second block is the center block among the blocks acquired by dividing the first block, and the dividing direction of the second block division mode is the same as the dividing direction of the first block division mode, then the second block division mode includes only a block division mode in which a division results in three blocks.

Abstract: An image encoder is provided, which includes circuitry and a memory coupled to the circuitry. The circuitry, in operation, performs a boundary smoothing operation along a boundary between a first partition having a non-rectangular shape (e.g., a triangular shape) and a second partition that are split from an image block. The boundary smoothing operation includes: first-predicting first values of a set of pixels of the first partition along the boundary, using information of the first partition; second-predicting second values of the set of pixels of the first partition along the boundary, using information of the second partition; weighting the first values and the second values; and encoding the first partition using the weighted first values and the weighted second values.
